17.14 individual cylinder trim
Set a compensation to each injectors output on a table that relates
engine RPM with individual cylinder trim compensation.
To use this compensation as a cylinder trim, the injectors have to be
wired with one output per injector.
This compensation usually brings expressive power gains when
correctly used, so, the use of one O2 sensor per cylinder is highly
recommended

17.15 Rotor compensation
Available only when controlling rotary engines, this is an individual
rotor fuel trim. This compensation usually brings expressive power
gains when correctly used, so, the use of one O2 sensor per rotor is
highly recommended.
17.16 Enrichment per gear
This option allows having a RPM based fuel compensation for each gear.
To enable this option, gear change detection must be enabled. It is
possible to set up to 6 compensation tables (6 gears).

17.17 Gear shift fuel enrichment
This function enables fuel compensation when a gear shift is detected,
that allows building a time based enrichment table.
NEW
This feature adds fuel when a
gear shift is detected. Enrichment
adds the fuel amount set up here
for the time duration set here aswell.

17.18 Fuel injection phase angle table
This table changes the moment, during the engine cycle, where the
injectors opens or closes and is only available when the fuel injection
is being controlled in sequential mode. The injection phase angle is
the distance, in degrees BTDC from the ignition TDC (0°) until the
moment the injector opens or closes (according to what is selected).
